Streptococcus pneumoniae, type 23F, resistant to penicillin (MIC, 2 micrograms/mL) and multiple other antimicrobic agents, was isolated from middle ear fluid of a child with otitis media attending a day care center in Ohio. To determine the extent of spread of this strain, nasopharyngeal culture surveys were done, and 52 carriers were identified among 250 children attending the index day care center. No carriers were found among 121 children at two other day care centers in the same urban area. Use of prophylactic doses of antibiotics (P < .001) and frequent use of antibiotics (P < 0.001) were risk factors for nasopharyngeal carriage. Carriers were more likely to have had frequent otitis media episodes (P < .02) and otitis media not responsive to antimicrobial therapy (P < .001). Strategies to limit the spread of highly resistant pneumococcal strains should include encouraging judicious use of antimicrobic agents and reevaluating indications for prophylactic use of antimicrobic agents.
Purpose
The purpose of this paper is to present a maturity model developed to assess knowledge sharing (KS) for the Jordanian construction sector.
Design/methodology/approach
The research was conducted in three stages. The first stage consisted of the review of literature and documenting variables from the literature that highlight influence on KS in organizations. The second stage was designed for maturity model development by identifying the cultural factors that affect KS in the Jordanian construction sector through questionnaires and interviews. Factor analysis was used to find possible relationships between the cultural variables followed by semi-structured interviews. In the third stage the initial maturity model was refined through another set of semi-structured interviews.
Findings
The model presented in the paper includes three levels of maturity. The first level identifies whether the variable barely exists in company’s KS practices. The second level shows the occasional techniques which the company uses to increase KS activities. The final level demonstrates the importance of the variable in affecting KS as being fundamentally ingrained in the company’s vision, mission, strategy and operations.
Originality/value
The research has developed a model that can be used to measure the KS in an organization. Although the model has been applied to the construction industry, it can easily be modified to fit in the other sectors.
On March 24, 2015, a Germanwings aircraft crashed in the Alps. The suicidal copilot killed himself and 150 others. Pilot suicide is rare, but does happen. This research analyzed the National Transportation Safety Board's accident database (eADMS) looking for pilots who died by suicide in flight. Fifty-one suicides were identified. Gender, age, and other characteristics were examined. Average age of suicidal pilots was 38, significantly different from the average age of 45 for all male pilots involved in aircraft accidents. A discriminant function accurately identified suicidal incidents at 96%. There was a high false-positive rate limiting the usefulness of the discriminant function.
This study explored gender-related perceptions among male and female pilots and the extent to which such perceptions may cause workplace stress, anxiety, or depression which may affect female pilots. This study utilized two measuring instruments on a sample that consisted of 83 pilots. The two measurement instruments used where the Aviation Gender Attitude Questionnaire (AGAQ) to measure gender bias and the Depression Anxiety Stress Scales-21 (DASS-21) to measure stress, depression, and anxiety among female pilots. There was a significant difference found between men and women across all AGAQ factors. While the results of this study concurred with research that suggests that female pilots are at greater risk for negative perceptions and sexism by male pilots, the results did not indicate any greater degrees of depression, stress, or anxiety in women as compared with their male counterparts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
